THIRD STREET TUNNEL PROJECT

The 3rd St Tunnel Project is the first of a multi-phase master planned development located in Washington’s central business district. Newly designed pedestrian and vehicular corridors will reconnect the Capitol Hill and East End communities, update traffic patterns, and deliver new safety features. The project is bordered by Massachusetts Avenue to the North, E Street to the South, Third Street to the West and Second Street to the East.
